eYc Air velocity conversion air volume calculation formula

Air velocity converted to air volume calculation formula is as follows

1. Circle Duct(Pipe inner dimension):

Radius(m) x Radius(m) x π x Air velocity(m/s) x Hour(Need to convert hours to seconds)= m3/h

Example:(0.025*0.025*3.1415926)*60(m/s)*3600(1 hour=3600s)=424 m3/h

DN50=50mm(Diameter)、25mm(Radius)= =0.025m


2. Square tube(Pipe inner dimension):

Side length(m) x Side length(m) x Air velocity(m/s) x Hour(Need to convert hours to seconds)= m3/h

Example:0.8*0.8*10*3600=23040 m3/h

● The above calculation formula ignores the installation angle, depth and pressure loss of the transmitter during installation
